Rose plant--Meinomad variety

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly and substantially continuously forms attractive double long-lasting bicolored blossoms which are Buttercup Yellow and are more or less edged and suffused with Cardinal Red coloration. The blossoms possess a slight fragrance. The plant exhibits a semi-erect growth habit, forms very vigorous vegetation, and forms attractive shiny dark green foliage which contrasts well with the blossoms. The plant exhibits good disease resistance, and is particularly suited for growing in parks and gardens.

SUMMARY OF THE INVENTION

The new variety of Hybrid Tea rose plant was created by artificialpollination wherein two parents were crossed which previously had beenstudied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was the product of the pollination of the Sonia variety (U.S.Plant Pat. No. 3,095) by the Rumba variety (U.S. Plant Pat. No. 1,919).In Europe the Sonia variety sometimes is known as the Sweet Promisevariety. The male parent (i.e., the pollen parent) was the product ofthe pollination of the Piccadilly variety (non-patented in the UnitedStates) by the Johnago variety (non-patented in the United States). Theparentage of the new variety can be summarized as follows:

    (Sonia×Rumba)×(Piccadilly×Johnago).

The seeds resulting from the above pollination were sown and 23 smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of Hybrid Tea rose plant of thepresent invention possesses the following combination ofcharacteristics:

(a) forms in abundance attractive long-lasting double bicolored blossomswhich are Buttercup Yellow and are more or less edged and suffused withCardinal Red coloration,

(b) forms blossoms which possess a slight fragrance,

(c) forms attractive shiny dark green foliage,

(d) forms very vigorous vegetation,

(e) exhibits a semi-erect growth habit,

(f) is particularly suited for growing in parks and gardens, and

(g) is not particularly affected by cryptogamic diseases.

The new variety has been found to undergo asexual propagation by anumber of routes, including budding, grafting, cuttage, etc. Thecharacteristics of the new variety have been found to be strictlytransmissible by such asexual propagation from one generation to anotherin France.

The new variety has been named the Meinomad variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety were two years of age and were observed during Junewhile budded on Rosa froebelli understock and growing outdoors at LeCannet des Maures, Var, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The description is based onthe observation of two year old plants made during June while budded onRosa froebelli understock and growing outdoors at Le Cannet des Maures,Var, France. The coloration in common terms precedes reference to thechart.
